MANIFOLDING PAPER.

Application filed March 11,1921. Serial No. 451,626.

To all whom it may concern."

Be it known that I, JOHN Q. SHERMAN,

a citizen of the United States, and a resident of the city of Dayton, inthe county of Montgomery and State of Ohio, have invented certain newand useful Improvements in Manifolding Paper, of which the 1 followingis a full, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification. l

My invention relates to improved methods of punching manifolding papers,so as to ,present a series of holes for engagement by aligning pins,said pins normally serving to both align andfeed a plurality of webs ofpaper.

The paper ,emplo ed in my invention is with some such mechanlsm as isshown and described for the first time in the pat ent to =Schirmer No.940,481, dated November. 16, 1909, wherein an autographic register isdescribed having rotary pin bearing bodies and certain other mechanismsadapted to store and support a plurality of continuous webs of paper.

There are many other forms of feed pin manifolding'devices, however, andmy invention may be employed with any devices wherein pins are movedthrough a path adapted to feed and align a plurality of webs of paper. ia

The usual manner of printing and cutting the webs of paper for usein-manifolding machines, is to print up a wide web in a press and punchthe holes therein, while printing. is. being done, and then slit the webinto the desired number of forms.

In this way a certain degree of accuracy is paper will have formsmaintained, so that all of the sections of the printed thereon, in

itself, and varying conditions of its manufacture and of moisture andother atmospheric conditions and the like, it is not pos sible to obtainperfect accuracy either 111 printing, punching the holes, or slitting.up

the various forms, or in-maintaining the proper and correct spacingbetween holes. under difi'erent atmospheric conditions, so

that somewill be Wider than others in the same cross section of a largeweb, and some longer than others. The discrepancies, in a single set offorms, are too slight to detract from their full manifolding value, butprovision must be made for taking care of discrepancies each time'theyappear to preventan accumulation of error, with a resultantmis-alignment.-

ere'only a few superimposed webs of paper are to be fed by means oftraveling pins, the chance discrepancies may usually be taken care of byfair size punch holes and smaller pins, the size of the holes being suchthat the pins will readily enter them and not bind against their edges;but for a larger number of copies and .often for a lesser number, theholes cut with due care will yet ride up on the pins and start a tearingof the paper. This may occur, as noted from the webs being of difi'erentlengths, the spacing of the holes of Varying width for differentsuperimposed webs and such like reasons. i

If only one form was fed slight discrep- F ancies inpunching would notalways prevent proper feed, but where several copies are fed, thediscrepancies, particularly those given .a' chance to adjust themselvesbecause of the discrepancy in punching. When not held down by the topsh'eet,if the holes in the under sheets are unched too far apart, theywould have a tendency to buckle; that is, the holes would be broughttogether and forced 6 over the pins to a certain extent as when one copyis fed. The top sheetholdingldown the other copies, however, will keepthem flat, thus causing the wider and narrower punched forms to overlapthe feed holes of the properly punched forms, and the feed punch throughthe nonpunched portions of the improperly punched forms.- This permitsthe pins to obtain a purchase-on the forms and causes wrong feeding bythe vplnsin the feeding operation .will then forms immediatelyriding'over the pins.

The overlapping caused by differences in the pins, which have a fixedspacing both the various copies of a set of manifolding forms is thegreatest difficulty in feeding them.

Discrepancies, occur in goods, been manufactured perfectly, have beenshipped, by changed atmospheric conditions that cause the forms toshrink when dry, orexpand with-increased moisture. between variouscopies that have The varlations is particularly noticed at such times,espeeially where different colors, qualities and weights of paper areused in the same set; the. extent of the variations from the standard orcorrect punching depending on the quality, weight and grades of stock,some of which are more susceptible to atmospheric conditions thanothers.

According to my invention,

- difliculty due to this inaccuracy of printing that is un-controllable,so far as l am advised, ll punch holes in the paper (in the properrelative position to the printing), which vary widely from exactsimilarity to the sizes of the pins, and soarrange them that one side orthe other of the webs will be acting as aligning and feeding elements,while the other side will not interfere with this proper feedby actingin a different manner.

As will be noted ll show many forms of structure for accomplishing myobject,-

which same is accomplished by that certain construction and arrangementof parts to be hereinafter more specifically pointed out in the threefigures and claimed.

In the drawings, v 1 v Figure 1 is a plan view showing a pin wheel feedand a plurality of webs of paper my invention and the discrepancies andthe manner of avoiding difficulties because'of them.

Figure 3 is another view showing, in the same manner, a still difiere'ntform, the feed being in the direction of the arrows.

Figure 4: is a perspective view showing a series of webs punched ,as perthe form shown in Figure 1, illustrating how one edge e of a wide pressstrip may be looser than the other.

- Figure 5 is a like view showi parts as in Figure 4 and show ng how 'acrease in the press strip. will throw. the printing and punchingoutof'true position. Figure 6 is a plan view showing another arrangement ofalignment holes;

'justmentover the pins as the same.

verse line as the feed pins,

fora feeding at all times and an alignment at all times and do away withchances for laterally and longitudinally of the machine, to work intothe paper at some nonapertured point.

The punching arrangement comprises dif ferent punchings or apertures,which T will designate as transversely elongated holes T, extra largeround holes F1, longitudinally extending holes L, and normal sizedholes, such as will form a loose but accurate fit over the pins, as atN.

Taking up the various figures of the drawings, Figure 1 shows three websof paper 1, 2, and 3, in which one margin is punched with holes T andtheother margin with holes N.

The pin wheels 4: are on a shaft 5 and, as will be observed, the pins 6at the holes N are in engagement with each web and in the act of feedingall three webs with the holes therein and the printing thereon inaccurate registry.

The pins 7 on the other sideare engaging in the holes T and thediscrepancy in width of the webs is such that web 2 is narrower gage inthe same part of the hole for each web by any means.

" The feeding will, in such cases of dis progress without tearing theboth sets of holes will assist in the longitudinal alignment of thevarious webs of paper while the set of holes N will crepancy,

' do all of the transverse'alignment.

The striicture shown in Figure 2 com prises three webs of paper 1, 2,and 3, and the holes in one margin are of the type termed 1R, whereasthe holes in the other margin are of the type termed N.v I lit can beappreciated that the large holes will permit of the same nature ofself-adthe holes T in the first form described. The feeding walls of thelarge holes lit are preferably on. the same transverse line as the likewalls of'the normal holes, the transverse line being what ll may termthe feeding line.

Taking up next the form shown in Mill )llll) Figure 3, it will be notedhere that there are webs 1, 2, margin to the left of the webs, the holesare of the type T, while the holes L. lln this type the lateralalignment is taken care of by the holes L, while-the the holes T. Bothsets of holes mayhave their feeding walls,

' so that both sets of holes act as feeders.

This combination is especially valuable because the laterally elongatedholes allow and 3, and that along the Mid other margin has longitudinalalignment is taken care of by I on the same trans= for discrepanciescaused by different widths appearing between the two rows of holes on Ihave found that this method of punching will permit me to operate anunlimited number of forms and maintain them in perfect alignment witheach other and thatit absolutely eliminates any possibility of theformscreeping away from each other or riding over the feedpins becauseof slight variations. Indeed, while in manifolding registers of the pastit has been found almost impracticable to feed and align by pin wheeldevices as many as six forms; with the above form of forms is merelyrestricted to that number through with legible copies can be made.

I have heretofore explained the chief difficulties of handling a numberof overlapped forms, as an example of the difficulty if a number of thinsheets of paper punched as for a loose-leaf book are taken, any one cansee at once how hard it is to get all the holes of a number of piecesinto a true line. My invention enables an ordinary autographic registerto .be free of this difliculty, no matter how many forms are used,provided that the punching is done with a fair degree of accuracy.

In one sentence it may be said'of this form that the laterally elongatedholes maintain alignment longitudinally and provide for discrepancieslaterally, .and the longitudinall elongated holes maintain alignmentlatera ly and provide for' discrepancies longitudinally, while both setsof holes act as feeders.

My feeding devices will operate with the feeding walls-or edges out ofthe true feeding line. i. e where the feeding edges of the one row ofholes is ahead of the feeding pins for that row. If the pins in thelongitudinal elongated holes in such an instance did not feed because ofnon-contact with the feeding edge of the holes, the pins would at leasthave plenty of clearance and not foul the paper, and the other pins inthe other assistance. 1

However, should-the operator abuse the feeding device, thu's indentingthe forward edges of the holes in the single series of holes that areactually doing the feeding under this circumstance, by jerking thehandle, or other means of abuse, such as laying the hand on the formswhile being'fed series of holes would properly feed without out, etc,the other pins. would soon' come .in

contact with the forward ends of the elongated holes-this contact ofcourse depend web l0'is shown as punching, the limit ofv of theindentation in of the other holes necessary such contactand as soon ofthe other series of pins ing upon the extent the forward'end to bringabout as this contact takes place, feeding assistance will be giveh tothe other series ofpins, thus bringing about normal feeding conditionsbefore the forms can be torn, and thus improperly fed. This condition.would be brought about by the combination of two or more series ofholes where one of theseries was longitudinally elongated.

Figures 4 and 5 show graphically how in the printing of plural copies,differences in length and width of the forms, and hence of the punchingspaces may occur, due to imperfectly manufactured paper, and this isoften the case. In Figure 4 the press paper printed into three sets offorms on lines 11, 12, and 13. The edge 14 of this press web is loosewhile is tightand hence in the printing or at least in the punching,-theholes will not come in uniform spacing from each, other lengthwise .ofthe form, particularly when the forms are slit apart and superimposed.

In Figure 5 is shown a press paper web 16 printed into forms 17 18, and19 and with a crease, fold, or wrinkle in the paper as at 20. .Theresult of the crease will be that when the paper is'straightened out, asin rolling it into small rolls, after being slit from the wide pressweb, the spacing of the holes laterally as well as longitudinally of theindividualwebs will be at variance.

In the forms of punching in Figures 6 and in the paper of the edge 15holes L on bothmargins in the form of Figure 7. As can paper, but willnotact to closely align the webs in the direction in which the'holes arethemselves extended. In the form in Figure sionally to bring all thewebs into lateral alignment. In the same way, large holes 22,

in the web in Figure 7, will act occasionally webs longituto align thesuperimposed be seen, these twoforms will operate with large numbers ofwebs of dinally. as in my co-pending application Serial N 0. 161,940filed April 14, 1917.

It will be noted that while .I have described all of the holes for eachset or longitudinal row as being the same throughout for that row, sothat taking Figure 3 for example, the row to the right may alternateholes T and holes L and the same for the row to the left; In such a caseI would prefer that thefeeding izo that this plan may be varied,

walls of theholes be always on the true N feeding line transverse'thepaper and that a horizontal and lon itudinal hole will alwaysbe'opposites for tfie two pin wheels. I do lab not desire to be limitedto the number of rows of holes, as any number more than one will beincluded in my" invention.
